Title: Unlocking commercially chipped B5 S4 ecm for Nefmoto flash Post by: OttoStadt on December 10, 2013, 08:43:08 PM First time posting, please be kind, I'm getting mixed info from sources around me and search isn't helping.
I have a commercially tuned/chipped (soldered chip in ECM) ECM in a 2000 S4 that I just bought and I'm upgrading it to Stage 3 fueling (85mm hitachi MAF/630cc inj). K04s/clutch is already in the car. can i use Nefmoto to flash the current chipped ECM I have to a different tune found in these forums? I have been told that once an ECM has had a chip soldered it can't be flashed and that I should locate a new virgin ECM (which appears to be an issue both in the timeframe I have and that I'd like to save spending the money if I can) Thanks for the help, Title: Re: Unlocking commercially chipped B5 S4 ecm for Nefmoto flash Post by: nyet on December 10, 2013, 08:46:14 PM if there isn't a daughter card you can flash over it with boot mode.
if there is a daughter card, you will have to desolder it and replace it with a stock (or blank) flash chip. if blank, you will need boot mode to flash over it.

I'll open the ECM up tomorrow to see what's inside. thanks again Title: Re: Unlocking commercially chipped B5 S4 ecm for Nefmoto flash Post by: OttoStadt on December 10, 2013, 08:51:27 PM In order to flash in boot mode the only way of doing so is to have a Galletto interface correct?
nefmoto/rosstech cable in dumb mode won't work?

You can use nef/rt cable as well, but you have to patch the galletto .exe http://nefariousmotorsports.com/forum/index.php?topic=3088.0title= Title: Re: Unlocking commercially chipped B5 S4 ecm for Nefmoto flash Post by: OttoStadt on December 22, 2013, 12:30:15 PM Hey Nyet,
So I'm working on this today, just opened up the ECM and I can't tell if anything was soldered inside (either way no daughter/out of place chip) there is a hand written sharpie mark on the ECM cover though saying "APR A box" so one would assume it's an APR ECM/flash. Boot mode/Galette/ross tech in dumb mode and I'll be all good to flash a base file from the tuning section, right? my ecm is a 8D0 807 551 A btw, planning on using the base file found here (i have piggie pipes, 3" neuspeed exhaust, FMIC, 044 pump, 630cc inj and hitachi maf/85mm housing): http://nefariousmotorsports.com/forum/index.php?topic=636.0title= I appreciate your help, thanks again!! |
